A new regime for analyzing properties of topological materials A pair of studies demonstrates how two related metal alloys, cobalt monosilicide and rhodium monosilicide, can convert light into electric current efficiently thanks to their topology. A pair of new studies demonstrates that two metal alloys are able convert light into electric current efficiently thanks to their topology. This fundamental research could provide a new approach for developing devices such as photo detectors and solar cells in the future.
Two recent studies demonstrate that there is a topological origin of two related metal alloys’ ability to convert light into electrical current. New fundamental research on rhodium monosilicide (RhSi), published in
Treasure Coins: Ancient Gold Coins Recovered From Shipwrecks
Dokos Shipwreck, the oldest in the world, was discovered by the father of underwater archaeology,
Peter Throckmorton, after almost four thousand years on August 23, 1975. A simple pile of ceramics and stone anchors and other stone items devoid of all biodegradable organic material, this wreck, unfortunately, contains no coins for one simple reason: the wooden vessel sank beneath the waves almost 2,000 years before the first coins were struck from electrum in
Lydia.
Since then,
UNESCO estimates that over three million other vessels have joined the Dokos shipwreck at the bottom of the ocean. Today, approximately 85% of all trade is transported by ship, and this percentage was greater in the ancient world. Ancient shipwrecks were mainly filled with amphora, “the cargo containers of the B.C. world” (Villano). These vessels, however, carried both physical and cultural goods, and it is possible to trace not only trade

Researchers from Skoltech and their colleagues have optimized data analysis for a common method of studying the 3D structure of DNA in single cells of a Drosophila fly. The new approach allows the scientists to peek with greater confidence into individual cells to study the unique ways DNA is packaged there and get closer to understanding this crucial process s underlying mechanisms. The paper was published in the journal
Nature Communications.
The reason a roughly two-meter-long strand of DNA fits into the tiny nucleus of a human cell is that chromatin, a complex of DNA and proteins, packages it into compact but very complex structures. To study the way DNA is packaged, researchers worldwide have developed so-called chromosome conformation capture (3C) techniques, the most efficient of which is called Hi-C. Hi-C essentially catalogs all interacting fragments of a DNA strand via high-throughput sequencing.

Photorespiration is a highly energy consuming process in plants that leads to the release of previously fixed CO2. Thus, engineering this metabolic process is a key approach for improvement of crop yield and for meeting the challenge of ever-rising CO2 levels in the atmosphere. Researchers led by Tobias Erb from the Max Planck Institute for Terrestrial Microbiology in Marburg, Germany, have now succeeded in engineering the TaCo pathway, a synthetic photorespiratory bypass. This new-to-nature metabolic connection opens up new possibilities of CO2 fixation and the production of value-added compounds.
